Description

This is a specialist role for someone who has genuinely built and operated Data Vault 2.0 pipelines on Snowflake at enterprise scale — not someone who has read about it. If that's you, the work is serious, the client is credible, and there's real runway beyond the initial contract.
The engagement
Remobi is placing a Senior Data Engineer into a major European energy business
You'll be a core contributor to an enterprise data platform — Snowflake-based, built on Data Vault 2.0 principles — that underpins planning, analytics, and reporting across the organisation. The contract runs until September 2026 initially, with a strong likelihood of extension for the right person. Fully remote, B2B .
What you'll be doing
  1. Designing and building scalable data pipelines across raw, harmonisation, and data mart layers
  2. Implementing and evolving the Data Vault 2.0 harmonisation layer — Hubs, Links, Satellites, and Business Vault patterns
  3. Handling the full range of CDC patterns: full loads, incremental loads, log-based and snapshot-based approaches
  4. Optimising Snowflake query performance — warehouse sizing, clustering, materialisation, cost governance
  5. Implementing automated data quality rules, lineage tracking, and reconciliation processes
  6. Designing and delivering well-documented, reusable data products for BI and analytics consumption
  7. Working directly with business stakeholders to translate requirements — you'll need to communicate as well as you can code
What you need to bring
Essential
  1. 3+ years of hands-on data pipeline development and/or data modelling experience
  2. Demonstrable Data Vault 2.0 experience — ideally greenfield builds, not just maintenance
  3. Advanced SQL — window functions, CTEs, performance tuning
  4. Experience with at least one ETL/ELT framework: dbt, Airflow, ADF, Fivetran, or similar
  5. Fluent English and availability to work German business hours (CET/CEST)
